Volkswagen Golf engine intermittently loses power at 2200-2600 rpm with potential cylinder misfire issue on Volkswagen Golf

Some Volkswagen Golf owners report experiencing intermittent power loss at 2200-2600 rpm, which may indicate a cylinder misfire issue. Symptoms can include a rough-running engine, stalling, and excess vibration, particularly at lower RPMs, along with decreased fuel mileage. Potential causes of this misfire include vacuum leaks, faulty spark plugs or ignition coils, and issues with broken valve springs or stuck valves that affect compression. Owners are advised to check for fault codes, perform leak down testing, and inspect spark plugs and ignition coils for wear or damage. To resolve these issues, it is crucial to repair any vacuum leaks, replace faulty spark plugs and ignition coils, and address any valve or compression problems to maintain optimal engine performance and reliability.
